This thesis explores the potential for integrating established e-commerce success factors (ECSF) into service-oriented e-business (SOEB). It examines whether traditional e-commerce principles can be adapted to SOEB practices. The research follows a dual-path approach, analyzing the SOEB literature and comparing empirical data from SOEB practices with this literature, as well as conducting a parallel comparative analysis of ECSF to determine which factors are relevant in the context of SOEB. Our findings reveal that while ECSF cannot be directly replicated in SOEB due to different operational contexts, many ECSF are naturally aligned with SOEB domain needs, but require contextual adaptation. Key success factors such as customer relationship management & customer support, personalized service delivery, platform usability, and robust security measures are important for both domains. The study also highlights the growing importance of servitization and social sustainability in SOEB, reflecting a shift in consumer values toward more socially responsible business practices. A theoretical model was developed to illustrate the transferability of ECSF to SOEB. This model distinguishes foundational factors already integrated to SOEB and identifies new factors for future exploration. It serves as a practical framework for industry practitioners seeking to extend SOEB operations through the use of e-commerce strategies. The research contributes to the academic discussion by bridging the unexplored gap between e-commerce and SOEB literature and presents an approach to incorporate ECSF to SOEB contexts. Future research directions include empirically testing the theoretical model, exploring additional e-commerce success factors, and investigating the role of emerging technologies and social sustainability in SOEB.
